Question

Currently I using ITextSharp for exporting my gridview to pdf. My gridview have an Image file and it's width will expend to 125% and height also to 125% percent. My questions are:

• how do i set the image to widht:80px and height:100px.

• after set the image width and height, how to insert it to the gridview?

besides that, after i export the gridview to pdf file, the image will go out of the cell. What is that and how to solve?

See this post in MikesDotnetting . Another post about working with tables in iTextsharp is also there

See a sample code for working with tables

// adding content to iTextSharp Document instance
                PdfPTable table = new PdfPTable(3);
                //actual width of table in points
                table.TotalWidth = 500f;
                //fix the absolute width of the table
                table.LockedWidth = true;
                //relative col widths in proportions 
                float[] widths = new float[] { 1f, 2f, 1f };
                table.SetWidths(widths);
                table.HorizontalAlignment = 0;
                //leave a gap before and after the table
                table.SpacingBefore = 20f;
                table.SpacingAfter = 10f;

  //Start Heading
                table.AddCell(new PdfPCell() { BorderColor = BaseColor.LIGHT_GRAY, Phrase = new Phrase("No.", new Font(Font.FontFamily.HELVETICA, 8f, Font.BOLD)) });
                table.AddCell(new PdfPCell() { BorderColor = BaseColor.LIGHT_GRAY, Phrase = new Phrase("Item Name", new Font(Font.FontFamily.HELVETICA, 8f, Font.BOLD)) });
                table.AddCell(new PdfPCell() { BorderColor = BaseColor.LIGHT_GRAY, Phrase = new Phrase("Description", new Font(Font.FontFamily.HELVETICA, 8f, Font.BOLD)) });

// Table content
//Here we can use a loop to add multiple rows
table.AddCell(new PdfPCell() { BorderColor = BaseColor.LIGHT_GRAY, Phrase = new Phrase("1", new Font(Font.FontFamily.HELVETICA, 8f, Font.NORMAL)) });
                table.AddCell(new PdfPCell() { BorderColor = BaseColor.LIGHT_GRAY, Phrase = new Phrase("Register Book"), new Font(Font.FontFamily.HELVETICA, 8f, Font.NORMAL)) });
                table.AddCell(new PdfPCell() { BorderColor = BaseColor.LIGHT_GRAY, Phrase = new Phrase("Used to manage the details"), new Font(Font.FontFamily.HELVETICA, 8f, Font.NORMAL)) });

Here you can see a three column table. For adding multiple rows you can loop the table content part in the code.

Pass the values from code as shown.
